Definitions
- the invention relates to threaded tubular components and more specifically to protectors for protecting the end of these components, in particular drilling tubes or operating tubes for oil or gas wells.
- tubular component means any element or accessory used to drill or operate a well and comprising at least one threaded end, also called a connection or connector, and intended to be assembled by a thread to another tubular component to form with this other component a tubular threaded joint.
- the tubular component may for example be a relatively long tubular element (in particular about ten meters in length), for example a tube, or even a tubular sleeve of a few tens of centimeters in length, or even an accessory of these tubular elements (suspension device or "hanger”, section change part or "cross-over", safety valve, connector for drill rod or "tool joint", “sub”, and the like).
- tubular components are generally assembled together to be lowered into hydrocarbon wells or similar wells and constitute a drill string, a column of tubing (“casing”) or tubing (“liners”). ”) or even a column of production tubes (“tubing”) (operating columns).
- API 5CT specification issued by the American Petroleum Institute (API), equivalent to the ISO 11960 standard issued by the International Standardization Organization (ISO), governs the tubes used as casing or tubing, and the API 5B specification defines standard threads for these tubes.
- API American Petroleum Institute
- ISO International Standardization Organization
- API Specification 7 defines stepped threaded connections for rotary drill rods.
- the threaded connections most often comprise one or more threads whose threads are substantially trapezoidal and comprise an engagement flank (called “stabbing") on the side of the threads directed towards the free end of the threaded element in question, a load-bearing flank (called “loading") on the opposite side of the engagement threads, a thread crest of non-zero width and a thread bottom of equally non-zero width, the load-bearing flanks and the engagement flanks being oriented substantially perpendicular to the axis of the threaded element (for example, the API Buttress thread has, according to the API standard, an inclination of +3° for the bearing flanks, and an inclination of +10° for the engagement flanks).
- the aforementioned tubular components may comprise a threaded male end which is intended to be screwed to a threaded female end of another tubular drilling or operating component. It is therefore essential that their male and female ends are damaged, polluted and deteriorated as little as possible between the time they leave their production line and the time they are used, but also between two successive uses. It will be understood that it is indeed necessary to protect against corrosion, dust and shocks (or blows) not only the thread, but also any bearing surface(s) and stop(s) which each have specific and complementary functions. , in particular with a view to ensuring sealing during the use phase.
- Protectors are devices whose function is to protect the functional surfaces of the male connections or of the female connections. These functional surfaces can be one or more thread(s), one or more bearing surface(s), one or more abutment(s).
- a protector is generally substantially cylindrical in shape and generally comprises a body, a securing means and possibly a mechanical shock absorber called a bumper located at the end opposite the free end of the protector.
- the generally suitable solution for attaching a protector to a connection is to screw it onto the thread of the connection. This solution allows a simple assembly gesture associated with precise positioning.
- the protector therefore comprises a thread suitable for being screwed onto the thread of the connection. The thread is most often of the same type and the same pitch as that of the connection.
- a protector thread therefore comprises threads with engagement flanks on the side of the threads oriented towards the free end of the protector and intended to come into contact with engagement flanks of the threads of a connection when the protector is screwed onto the connection, bearing flanks, thread crests and bottoms and at least one abutment.
- the main purpose of a protector is to protect the connection of a tubular component (intended for drilling or operating hydrocarbon wells or the like) against various types of external aggression: mechanical damage such as shocks mechanical, pollution (chemical and material) such as dust settling on functional surfaces and corrosion of materials between the time the tubular component leaves its production line and the time it is used (with several possible assembly-disassembly protective device).
- An idea at the base of the invention is a protector making it possible to protect a threaded end, in particular during transport and storage thereof.
- Another idea underlying the invention is a protector which, once mounted on a threaded end, does not unscrew unintentionally.
- Another idea underlying the invention is a reusable and adaptable protector, that is to say one that can be modified in order to adapt to different types of connections.
- Another idea at the base of the invention is a protector which facilitates the cleaning of the grease at the bottom of the protector, in particular on the smooth parts of the protector.
- Another idea underlying the invention is to provide a reliable and economical protector by the possibility of replacing the thread of the protector only instead of the protector in its entirety.
- the invention provides a protector to protect a male or female threaded end of a tubular component for drilling, exploitation of hydrocarbon wells, transport of oil and gas, transport or hydrogen storage, carbon capture or geothermal energy, the male or female end being provided with at least one external or internal thread, the protector comprising:
- main body intended to receive the male or female threaded end, the main body comprising a peripheral side wall extending in an axial direction, in which a housing is arranged in a thickness of the peripheral side wall, said housing extending around the peripheral side wall,
- the protector can be inserted on a male or female threaded end in order to protect it. Also, part of the protector is reusable. Indeed, the threaded ring initially housed in the housing of the protector can be replaced by another threaded ring, which gives the protector an adaptability allowing it to be reused for the same male or female threaded end or a threaded end comprising a thread different.
- the threaded ring and the housing contribute to creating thread interference and thus adding more torque value to the protector.
- a protector according to the invention allows quick and reliable assembly and disassembly on site of the protector on a tubular component connection and allows easy inspection of the condition of the threads before use or between two successive uses of the component.
- a protector according to the invention makes it possible to prevent premature or unwanted unscrewing of said protector. Indeed, an axial force associated with a rotation must be provided to allow the initial assembly of the protector on a tubular element.
- the ring When the protector is in the screwed position, the ring is in the screwed position on the tubular threaded element.
- the main body can be caused to move around the tubular threaded element without the protector dissociating from the connection to be protected. Only the application of a reverse rotation and possibly an axial force will allow disassembly of the guard.
- a transmission of force between the threaded ring and the body of the protector can take place in different ways, for example by friction or by gearing.

- Figure 12 illustrates a protector which also makes it possible to block by friction a rotational movement of the threaded ring 8 during the screwing of the tubular component.
- the thickness of the threaded ring 8 is greater than the depth of the housing 7 so that the threaded ring 8 is slightly projecting.
- the tubular component 10 has a diameter slightly greater than the initial diameter of the threaded ring 8.
- Figure 13 illustrates a protector 1 according to another embodiment comprising a housing 7 and a threaded ring 8.
- the threaded ring 8 is visible in perspective in Figure 14.
- the threaded ring 8 is helical in shape and comprises two turns distant from each other around the same axis X.
- the threaded ring 8 is interrupted, that is to say that the two ends of the threaded ring 8 do not meet.
- the housing 7 is hollowed out in the thickness of the internal wall 42 of the peripheral side wall 4 and has a shape corresponding to the helicoid of the threaded ring 8.
- the threaded ring can be inserted and maintained in the housing 7 in order to allow the screwing of a male threaded end of a tubular component.
- Figures 15 to 17 show a protector 101 for protecting a tubular component 110 having a female threaded end, that is to say having an internal thread. Elements similar or identical to those of the preceding figures bear a reference numeral increased by 100 with respect to the preceding figures.
- Figure 15 illustrates a protector 101 comprising a main body 102 intended to be inserted into the female threaded end portion.
- the main body 102 comprises a bottom wall 103 and a peripheral side wall 104 extending from the bottom wall 103 in an axial direction X all around the bottom wall 103.
- the peripheral side wall 104 has an upper end spaced from the bottom wall 103.
- a lower seal 105 is located on the bottom wall 103 and is intended to establish sealing contact with an internal surface of the female threaded end.
- An upper seal 106 is located on the upper end and is intended to establish sealing contact with an outer surface of the female threaded end.
- An outer surface of the peripheral side wall 4 of the main body 2 has a housing 107 located between the lower seal 105 and the upper seal 106.
- the housing 107 is formed in a thickness of the outer surface of the peripheral side wall 104 and extends around the peripheral side wall 104.
- the housing 107 is intended to receive a threaded ring 108.
- Housing 107 has an upper flange 171 intended to stop the threaded ring 108 in the axial direction X, in the direction of the upper seal 106 and a lower flange 172 intended to stop the ring in the axial direction X, towards the bottom 103.
- a threaded ring 108 is housed in said housing 107 in a removable manner, the threaded ring 108 has a thread 181 on an outer surface of the peripheral side wall 104 in order to allow the screwing of the protector 100 on the female threaded end, i.e. on an internal thread.
- Figure 16 illustrates a tubular component 110 and a corresponding protector 100 screwed onto said tubular component 110.
- the bottom wall 103 and the lower seal 105 have a through hole 131 which is intended to receive a tenon 21 of a plug inner 20.
- the tubular component 110 has a female threaded end, that is to say having an internal thread 14.
- the lower joint 105 establishes a sealing contact with an internal surface of the female threaded end and the outer joint 106 established sealing contact with an outer surface of the female threaded end.
- Figure 17 shows an exploded view of the protector 101 shown in Figures 16 and 17.
- the tubular component 110 is generally cylindrical in shape and has a female threaded end, that is to say having an internal thread 14.
- the threaded ring 108 is interrupted in order to form an interruption zone 182 in the form of a staircase in a manner similar to FIG. 7 in order to be able to be deformed during insertion into the housing 107 or removal from said housing. 107.
- the housing 107 has an upper rim 171 intended to stop the ring in the axial direction, in the direction of the upper seal 106 and a lower rim 172 intended to stop the threaded ring 8 in the axial direction X, in the direction of the bottom 103 .
